| Comment: |
extended tripel-layer model (ETLM); site-occupancy standard states; both protonation and electrolyte adsorption parameters for the brucite surface were from a regression of surface titration data measured by [PS04]; protonation and electrolyte adsorption parameters recalculated for the estimated pHPZC, lateral As, and Ns using the methods detailed by Sverjensky (2003, 2005) |
